"provide a novel means for positively actuate 1ng a1revoluble inking plate step byv step. .30

"Another object is to provide -means for positively actuatin a revoluble plate n combination wit yielding means-tendin to prevent said plate from rotating an vibrating. i Q

In the accompanying drawings 67-1nd1cates an inkingplate rotatably -mo1inted on thebed plate 1 of a printing machine. The un-' den side of late 67 is provided with a circular row oi ratchet teeth 68 withwhicha weighted pawl 69 on anoscillating lever 70' rates, said row of teeth beingPooncentric' e axis of-th'e inking plate.. awl is pivoted at 69 to a'downwardly projecting ortion 72 on 'the outer end of lever 70,1sai

portion "72 being provided with}; a pm 73 which formsa-stop for the-pawl. .The lever 70 is provided at its inner-end with aooll'ar 71 which-surroundsa boss 68* on theunder side of the inking plate. The up portion 1 of boss 68is provided: withe which rests on the late'lj'and'ptev l qj Ki ate, saidmeans including a lever the inking plate from c ionallyeng'ag'ing 20 indicates a leaf spring interposed "be tween the boss 68 and a'd1sk 21,
